can you opt out of a forum?

Online forums work best if people only talk about the general topic of what the forum is about.
This way you don't really get to know the person behind what they type. This little boundary keeps most people polite and respectful.

Politics and religion expose the real inner thoughts and believes of people, and that's not/never what's in the best interest for a (car related) forum.

Perhaps, but I have a little different philosophy...

I see us all as friends. And as friends, we talk about many things, we tell jokes, talk about news, and sometimes even talk about cars. :) I want people to come here and spend time even when maybe they don't have something specifically car related to talk about..

However, because politics can be so volatile, I have it in a hidden forum you have to sign up for.
